ABSTRACT=<p><italic>Leptoporus</italic> is a rare and remarkable genus, mainly occurring in coniferous forests in the Northern Hemisphere. Recent phylogenetic studies showed that <italic>Leptoporus</italic> belongs to Irpicaceae in the phlebioid clade. It is worth noting that most species in the phlebioid clade can cause white-rot decay, except for the <italic>Leptoporus</italic> species, which can cause a brown-rot decay. In this study, we performed phylogenetic and taxonomic studies of <italic>Leptoporus</italic> and related genera. Molecular phylogenetic analyses were conducted based on sequences from multiple loci including the internal transcribed spacer (ITS) regions, the large subunit of nuclear ribosomal RNA gene (nLSU), the largest subunit of RNA polymerase II gene (<italic>RPB1</italic>), the second largest subunit of RNA polymerase II gene (<italic>RPB2</italic>), and the translation elongation factor 1-α gene (<italic>TEF1</italic>). Combined with morphological characteristics, a new species, <italic>Leptoporus submollis</italic> sp. nov., is discovered and illustrated from Southwest China.</p>
